Intraoperative holmium laser lithotripsy under cholangioscopic visualization for refractory intrahepatic stones / 中国微创外科杂志

ABSTRACT

Objective To investigate the techniques,safety,and efficacy of intraoperative holmium laser lithotripsy under cholangioscopic visualization for refractory intrahepatic stones. Methods A total of 38 patients with refractory hepatolithiasis underwent cholangioscopic holmium laser lithotripsy.The laser setting was the wavelength of 2.1 ?m,the maximum mean output power of 100 W,the pulse peak power of up to 6 kW,and the laser fiber of 400 ?m in diameter.Results The stones were entirely removed on one session in all the 38 patients.The lithotripsy time was 3~5 min,the times of fragmentation was 3~8,and a total of 65 stones were fragmented.No bile duct injuries or biliary leakage happened.Cholangiography and B-ultrasonography at 2 postoperative months found no residual stones.Follow-up for 6 months found no recurrence.Conclusions Application of holmium laser lithotripsy under cholangioscopic visualization for the management of refractory intrahepatic stones is safe and effective.
